Objective To detect the impact of ultrasound elastography in diagnosis of prostatic cancer,and to evaluate its capability in differentiating benign from malignant lesions.Methods From June 2013 to February 2015, we selected 50 patients with different prostatic lesions,and suspicious for malignancy were included.All patients had a conventional B-mode ultrasound examination and color Doppler imaging,and then real time ultrasound elastography was performed in the same session.Finally,the results were compared to the histopathological results of those lesions. Results The addition of Strain ratio parameter for evaluating the elastography images showed the highest sensitivity of 74.2%,specificity of 73.7% and accuracy of 74.0% at a best cut off point of 5.5 between benign and malignant lesions.Conclusion Prostate US combined with elastography can be a helpful tool for guiding malignant lesions.Also it can help in targeting the biopsy site.

[Objective] The aim of our study was to seek the mutations in MODY1～5 genes in Chinese population by direct sequencing in probands from families with early-onset type 2 diabetes.[Methods] Variants screening in MODY 1-5 genes were performed by PCR and direct sequencing in 19 probands from early-onset type 2 diabetes families.[Results] We found no mutation but many polymorphisms.There were 6,5,15,1,and 1 variants in MODY 1-5 genes respectively.[Conclusion] Our negative results in MODY genes suggest the genetic heterogeneity of different populations.Mutations in MODY 1-5 genes might not be the cause of diabetes in those 19 families.

Objective To investigate the effect of early insulin therapy on NF-KB pathway and inflammatory cytokine responses in fiver of diabetic rat.Methods NF-KB p65 DNA binding was assayed with ELISA-based assay kit,cytokine gene expressions were quantified with real-time PCR and phosphoenolpyruvate carboxykinase(PEPCK),NF-KB and inhibitor KB(IKBα)protein levels wlere assayed with Westem blot.Results Compared with control,hepatic PEPCK protein level in the untreated diabetic rat increased by 40%.Early insulin and gliclazide treatment normalized PEPCK protein level.The abundance of IKBα protein was significantly decreased and nuclear NF-KB p65 DNA binding activity was incteased in untreated diabetic rats.IKBot protein content increased and NF-KB p65 DNA binding decreased during early intervention treatment.mRNAs encoding IL-1β and TNFα were increased,which were reduced to normal levels after insulin and gliclazide treatment.Conclusions It is suggested that early insulin treatment inhibits NF-KB activity and inflammatory cytokine responses in fiver that are involved in the aniefioration of insulin resistance in diabetic rats.Such results misht be due to indirect antiinflammatory effects of insulin thus relieving glucotoxicity and lipotoxicity in pefipherM tissues.

Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.
